We multiply parentheses ..

(+x^2+1/8*24)-9=0

We multiply all the terms by the denominator


(+x^2+1-9*8*24)=0

We get rid of parentheses

x^2+1-9*8*24=0

We add all the numbers together, and all the variables

x^2-1727=0

a = 1; b = 0; c = -1727;
Δ = b2-4ac
Δ = 02-4·1·(-1727)
Δ = 6908
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

The end solution:

$\sqrt{\Delta}=\sqrt{6908}=\sqrt{4*1727}=\sqrt{4}*\sqrt{1727}=2\sqrt{1727}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-2\sqrt{1727}}{2*1}=\frac{0-2\sqrt{1727}}{2}
=-\frac{2\sqrt{1727}}{2}
=-\sqrt{1727}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+2\sqrt{1727}}{2*1}=\frac{0+2\sqrt{1727}}{2}
=\frac{2\sqrt{1727}}{2}
=\sqrt{1727}
